How do I call OpenVMS System Services from Java code?
We have packaged an example that demonstrates how to call OpenVMS System Services from Java code. It is a complete example that compiles and links everything it needs from the components on the demo kit file. It creates two classes LibGetJPI and LibGetSYI which act as jacket routines that call Java Native Interface (JNI) C-based native code that actually accesses the GETJPI and GETSYI system services.
